brown indicate good clay land mainly and heavy growth of useful timber from 

 7" to 16" in diameter mostly jack pine and spruce. 



A considerable area is ruggedly rocky especially on the east of Badland 

 Lake but in the vicinity there are some patches of rich loam.

Appendix No. 22 



Report of the survey for the dam site and a contour traverse of the proposed 

 storage basin on the Grand River, near Waldemar, Township of East 

 Garafraxa, in the County of Dufferin, surveyed by Speight & Van Nostrand, 

 O.L.S. Dated 2nd February, 1934. 



Sir:— 



Following your instructions dated October 19th, 1933, to make the neces- 

 sary surveys for the dam site and a contour traverse of the proposed storage 

 basin on the Grand River, near Waldemar, we have carried out the work as 

 instructed and report as follows: 



The dam site provisionally selected by the Power Commission was im- 

 mediately northeast of the allowance for road between Concessions XII and 

 XIII in the Township of East Garafraxa, lying in lot number 14, of Concession 

 XIII. Elevations were taken over this area and a plan prepared on a scale 

 of fifty feet to the inch. 



In order to obtain a datum for the work, it was considered advisable to 

 connect with the nearest geodetic bench mark, which proved to be on the 

 C.P.R. branch line running through Bell woods, and was about five miles from 

 the proposed dam site. 



The feature controlling the height to which it is feasible to raise the water 

 was considered to be the clearance under the C.P.R. bridge crossing the Grand 

 River at Waldemar. This clearance was fixed at four feet. Our levels show 

 that the lowest point on the main girders of the bridge was at elevation 1475.56. 

 A four foot clearance beneath this girder fixed the high water level at elevation 

 1471.56. Contour 1475, which had been spoken of in our preliminary discus- 

 sions as the elevation to which land should be bought, is 3.44 feet above the 

 water level so determined. It was thought advisable, however, to work to 

 the 1475 contour. No great amount of additional land is involved in the 

 extra fraction of a foot of height, as the limit of the flooded area is throughout 

 much the greater part of its length along well defined hillsides. 



The position of this contour was located at one hundred foot intervals 

 throughout, and was traversed with transit and tape. From this contour 

 additional contours were located by hand level. The four hundred and eighty 

 foot contour was located above the main contour, and for the most part, 

 three five-foot contours were located below. Where the land was heavily 

 wooded, however, or the contours widely separated, only the first contour 

 below was located, as it was felt that other information was more essential.
